How is Antarctic Bottom Water formed at Cape Darnley? With @oceanhelen.bsky.social and others we show:
❄️ Mackenzie Polynya boosts formation
🧊 Amery Ice Shelf melt suppresses formation
Important for future climate projections

One of my favourite emails to reach me this year: My @awi.de colleague send a message in a bottle to his kids from an #Antarctic expedition and the bottle reached my home #Tasmania after only 900 days at sea travelling 15,000km!
Quick work for the mighty #SouthernOcean!

Antarctica and the Southern Ocean hold critical clues about our changing climate – understanding this change is essential for communities worldwide.

🌏 Happy Antarctica Day! ❄️
Today we celebrate global cooperation in protecting and understanding one of Earth’s most unique and fragile environments.
A huge thanks to all our researchers for driving this work forward every day.

Thank you to the Parliamentary Friends of the Antarctic for hosting our information event at Parliament House this week, and particularly the co-chairs Senators Duniam, Whish-Wilson and Dowling of Tasmania for their tripartisan support of #Antarctic science.
So excited to work with this wonderful team!
We will be working on samples collected on land and marine campaigns during the last two Antarctic seasons and investigate how the Aurora Basin will react to a warmer climate! 🐧❄️🧊⚒️🧪
🌍 Last week, 140+ Antarctic scientists came together in #Hobart for our ACEAS Research Forum 2025 to share the latest research and insights about the climate risks emerging from #Antarctica and the #SouthernOcean.

How vulnerable is East Antarctica’s ice in a warming world? 🧊🌍
Thrilled to be awarded #ARC funding with my stellar collaborators!
We will explore geological archives that record how the ice sheet reacted to past warm periods — and what that could mean for our future.

"That is a crisis in terms of our ability as a nation to do the work we need to do to inform the policymakers, but also just to show that we take Antarctica seriously."

"The rocks that the glacier sits on impact the way it behaves, the heat that’s coming through the crust impacts the way that glacier behaves."

The best part about our icy research is sharing it!
Our calls with schools were certainly a highlight of the Denman Marine Voyage!

Very proud of my #IODP shipmates for spearheading this amazing paper on our new data from #Exp395.
We are looking at the onset of deepwater formation in the North Atlantic and its relation to Greenland‘s ice sheet.

Finishing the #Denman Marine Voyage with more outreach
I invited students from my old high school in Northern Germany to come on a virtual tour of RSV Nuyina. Through the @antarcticsciaus.bsky.social school outreach program, 96 year 11 students learned about the science we do on DMV: 🌊🧊🇦🇶🧪🦭🌡️🐙☁️
🐚 AAPP PhD student @utas.edu.au Nia Riengchan studies how acidification of the Southern Ocean affects the shell-building of small planktonic snails called 'sea butterflies'. Now, for the first time, she's able to watch their babies develop.

As the #DMV reaches its final days in #Antarctica, the last rock dredges are underway.
This one retrieved "just three rocks, but all the same so that is very good!" - @hochmuth.bsky.social, pictured with Jo Whittaker.

The major role of phytoplankton in reducing carbon dioxide in the atmosphere is well established, yet the factors controlling phytoplankton growth are still not fully understood.

Being able to monitor the overflow of #Antarctic dense waters from the continental shelf to deeper open waters is critically important, but has long been a major challenge for scientists.
New research from @matthisauger.bsky.social could be a game-changer ⬇️

Yesterday was our last day in the sea ice. I was really lucky to have experienced this amazing landscape with its adorable wildlife in the last weeks. We had a very successful science program in areas of East Antarctica never studied before 🌊 🧪
Goodbye Antarctica 👋🇦🇶🐧
#DMV
The #DMV has transited east and west of the Denman Glacier and the Shackleton Ice Shelf, and one side is markedly more biologically productive than the other.
